Dropped Wi-Fi Connections (Apple Only)
Apple's Private Wi-Fi Address feature, introduced in macOS Sequoia and updated for iOS 18 and iPadOS 18, can cause connectivity issues when using eduroam or CU Guest Wi-Fi if not set to "off."
OIT strongly recommends turning off Private Wi-Fi Address for eduroam and CU Guest. Learn more about these recommendations.
Note: Occasionally, OIT's updates to Secure Computing devices will inadvertently toggle this feature on. If you start experiencing dropped Wi-Fi connections, please check to make sure this setting is off.

CU Secure
CU Secure is available to all CU Boulder affiliates with an active IdentiKey; however, devices must be pre-registered on the network to connect.
- Secure Computing devices are already registered; no action is required. Learn if your business device is enrolled in CU Boulder's Secure Computing framework.
- Personal and non-Secure Computing devices need to be manually registered by installing the CU Secure certificate on each device.
Register a Laptop or Mobile Device
The installation process varies widely by operating system and user settings. For the smoothest experience, follow along with the instructions:
Connect to CU Secure
Once registered, your device should connect to CU Secure automatically for the next two years.
